ABSTRACT:
A hydraulic cylinder for steering a tiltable boat engine includes a cylinder housing with first and second housing ends. In the improvement, at least the first end includes a reduced-dimension relief portion preventing the cylinder first end from contacting the engine when the engine is tilted. A new method for making such a cylinder includes the steps of forming a cylinder housing having a mid-section and first and second housing ends and shaping a relief portion at the first end. The cylinder first end is thereby prevented from contacting the engine (and, particularly, the engine stern bracket) when the engine is tilted. The invention also involves unique manufacturing and assembly techniques.
